Toggle is a tool that allows for the dynamic re-configuration of specific service instances. It’s great for allowing developers to change features without having to restart the entire system and it can be extremely helpful when developing and testing new features or bug fixes. However, like all tools a developer must be aware of when using it and the potential problems that can arise from misusing it.

Toggles are used throughout modern interfaces and can be a great way to allow users to choose between options or to show/hide functionality. However, it’s important to use toggles with caution because they can be confusing to users when used incorrectly. Toggle switches should provide clear visual feedback to the user, indicating their current state through color changes or iconography. They should also be easy to interact with, ensuring that they respond reliably to user input.

It’s also important to make sure that a toggle switch has clear, concise labels that describe what the control will do when it is on or off. These should be read from left to right and be easy to understand. A good rule of thumb is to keep the labels short and direct, limiting them to no more than two words or two nouns. Additionally, it’s often best to avoid using neutral or ambiguous labels because they can create confusion for users. If possible, it’s always best to say the label aloud to ensure that it makes sense and that there isn’t any ambiguity.

In addition to the visual cues, it’s important that a toggle switch is properly positioned in the UI. Toggle switches should be placed in clear, prominent locations so that they are easy to find. They should also be clearly differentiated from other elements so that they stand out.

Finally, it’s important that a toggle does not require a user to click a Save or Confirm button for the change to take effect. This can be frustrating for users and can lead to a lot of unnecessary bugs. For this reason, it’s usually better to use a checkbox for these types of controls when they are present in long forms and where users would have to tap the Submit button for the change to take place anyway.

Toggle Configuration

Using static files to manage the state of toggles can become cumbersome as an application grows. It’s also difficult to ensure consistency across a fleet of servers when managing toggle configuration in this manner. For this reason, many organizations move toggle configuration into some type of centralized store, such as an existing application DB or an admin UI. This approach can help to reduce development time, improve production performance and ensure that any changes are rolled out consistently across the whole application.
